ZEBINA EASTMAN, OF CHICAGO. ILLINOIS.

Letters Patent No 90,513, dated May 25, 1869.

IMPROVEMENT IN RUNNING GEAR OF STREET-CARS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern Be it known that I, ZEBINA EASTMAN, of Chi;cago, in the county of Cook, in the) State of Illinois, at presentresiding abroad as the United States Gonsul at Bristol, England, haveinvented a new and useful improvement in the construction of the gearingor running'parts of the cars or carriages for horserailways,steam-railways, or common roads, which invention was patented in theUnited States Patent Otfice, dated the 9th day of October, 1866, No.58,621; and' whereas, I have since discovered new and importantimprovements in the construction of the same, and to be used inconjunction with the said patent, I hereby request further protection onthe same; and for that purpose, I do hereby declare the following to bea clear, full, and exact description of and the main reach in thecentres of each.

c isa bolt, which passes through a hole in the centre of thereaches,which is to be placed under the control of the driver, so that he. maylift it, by a pull cord, from its position in the centre hole, or let itfall back by its own weight into its position.

When the centre-bolt is down it has passed through all the reaches, andholds them fast, so that the axles will not radiate or oscillate, butare held firmly square across. the carriage, parallel with each other,and consequently, when so held by the bolt, the car will move only in astraight or direct line.

When at a curve, the driver will draw the bolt up, and the rods will beliberated to act upon the axles, and they will then freely radiate tothe curve, or circle in which the car is moving.

Figure 2 is a sectional side view of the same plan as fig. l, withthesame letters of reference to the same parts. t

What I claim as new,and desire to secure by Letters Patent, is-- I Incombination with the reach a, and crossed diagonal reaches 11 b, thecentre-bolt a, substantially as and for the purpose set forth.
